…the detected pronunciation. Start- and end time is in HTK units. 1 HTK unit is 100 nanoseconds, so dividing the times by 10000 gives the amount of milliseconds. Score is log likelihood ratio from {-inf,+inf} interval. Confidence is a probability from {0,1} interval. To convert it to percentage, multiply the confidence value by 100.

…User Calibration Mean Normalization Requirements: 100+ audio recordings from different speakers representing the source data, minimum 60 seconds net speech in each. Ideally, the set shouldn’t contain duplicates or target speaker recordings. Mean Normalization makes data coming from different domains comparable by compensating for the differences in channel, language etc. Mean Normalization is extremely lightweight and has little to no…

…of an empty recording SNR would divide by zero => is_valid would be false waveform_snr – the signal to noise ratio (SNR) describes the ratio of the useful signal to the noise signal it is measured in dB calculated from the waveform distribution, (silence – has Gaussian distribution, voice – has Gamma distribution); SNR = 20 * log10(S/N) technical signal…

Faster than Real Time (FtRT) metric is developed for defining software performance reference point. Using this metric you can collect “benchmark” data of real processing speed for reviewed software, which should be found – and reproduced – on exactly defined HW. Then, comparing various benchmarks result, you can compare performance of the specified software and its parts on different HW…
